577050301 - Spring for T25B Battery Trimmer Head

The Husqvarna Spring (Part #: 577050301) is a genuine OEM replacement component designed for the T25B trimmer head used on Husqvarna battery-powered string trimmers. This internal spring is essential for the Tap Advance line feed system, allowing the trimmer line to extend properly when the head is tapped during use.

Over time, the spring may weaken or become damaged, leading to inconsistent line feed or spool malfunction. Replacing it with this OEM spring ensures your trimmer continues to operate smoothly and efficiently.
